·At
power-up, press and hold SELECT, and then press and hold RESET.
You’ll get a completely empty playfield (picture #1). If you do this during a
game, the screen will show exactly how everything was when you did the trick.
This trick will cause the title screen to constantly stay on - the demo mode
will not appear.

·The
action will speed up when certain rounds are reached, and actually decrease
later in the game!

·BUG: The manual states you start with 5
lives, and can earn another 5 (at 20k, 50k, 100k, 150k, and 200k), but none
after that; however, you earn a free life if you roll the score (at 1 million),
and the same point values for free guys will still work..

·BUG: There’s technically only 128 levels;
after which the screens with values that weren’t intended, which results in
screens with either 1 or no rocks, so you can't get the bonus veggie points).

·BUG: If you stand in the lower-left corner
(at the very bottom, and no more than 2 body-widths away from the left edge –
picture #2) as the last enemy escapes, you’ll be killed! If you have any
reserve lives left, the enemy will likely reappear somewhere other than in a
tunnel (ex. in solid dirt or on top of a rock!). Another side-effect of this
bug affects the continue feature – you’ll start the new game several levels
ahead of where you left off.

·BUG: Although the manual says you can’t, you
can pump through a narrow column of soil if you’re very close to it.

·BUG: A rare glitch may appear after rolling
the score in which the ghost of a Fygar will suddenly appear somewhere.
